6. If there is no voltage reading at the wiring harness, check continuity of the 16 gauge blue wire from the
headlight to the light switch. Using a multimeter set to 20 volts DC, attach using an alligator clip, the
black (–) probe of multimeter onto the negative battery terminal and place the red (+) probe into the
blue wire terminal of the wiring harness. If the multimeter reading is approximately 12 volts, the blue
wire has continuity.
7. Check continuity of the 16 gauge black wire from the headlight to the ground terminal. Using a multim-
eter set to 20 volts DC, place the black (–) probe of multimeter into the black wire terminal of the wiring
harness and attach using an alligator clip, the red (+) probe onto the positive battery terminal. If the
multimeter reading is approximately 12 volts, the black wire has continuity.
